Description
Homochirality is an important problem for the comprehension of the emergence of life. Several models describe it as a symmetry breaking phenomenon from an initially racemic system, towards an asymmetric steady state. It will be shown how such a system can be built by an assembly of several simple chemical reactions, allowing the establishment of positive or negative feedbacks inside the reaction network, leading to dynamic unstabilities. The theoretical aspects will be developed, in relationship with experimental data.
